Has
your back been bothering you for months -- or
years -- and still you and your doctor haven't
been able to figure out why? You're not alone.
Back pain is the most common cause of job-related
disability in America, according to the National
Institutes of Health, and costs about $50 billion
a year in treatments. Some 80% of Americans will
experience back pain at some time in their lives.
But most cases of back pain can't be traced to
a specific, definable cause.
"It's a huge problem that we have for both
conventional and alternative techniques for treating
back pain," says Daniel C. Cherkin, PhD,
a senior investigator at the Group Health Cooperative's
Center for Health Studies (CHS) in Seattle. "With
this huge category of people who have what's referred
to as non-specific back pain, you can't trace
it to a particular cause."
This conundrum leads many back pain sufferers
to seek out "alternative" treatments
-- everything from massage and acupuncture to
mind-body therapies and exercise programs like
yoga and tai chi. For example, studies show that
back pain accounts for 20% of visits to massage
therapists and 14% of visits to acupuncturists,
Cherkin notes. But do any of these options work?
In many cases, the scientific jury is still out.
A recent review of dozens of studies looking at
massage, acupuncture, and spinal manipulation
(chiropractic) as treatments for low back pain,
led by Cherkin, showed some evidence pointing
toward the effectiveness of massage and spinal
manipulation, but less is known about acupuncture.
"The studies we reviewed found massage to
be effective for relieving symptoms and increasing
function among people with persistent back pain,"
Cherkin explains. "Spinal manipulation shows
small clinical benefits for back pain -- about
the same as conventional medical treatments such
as over-the-counter pain relievers and various
types of physical therapy."
Based on existing studies, the effectiveness of
acupuncture remains unclear, but a new, large
study recently launched at the Group Health Cooperative
aims to answer some of those questions. To be
conducted over four years, the study is recruiting
nearly 700 back pain sufferers and will compare
acupuncture to conventional care.
Building a Stronger Back
"The most predictable way of resolving back
problems, based on the scientific literature,
is by increasing strength," says Vert Mooney,
MD, director of U.S. Spine and Sport in San Diego.
"There's good evidence that with chronic
back pain, the muscles around the spine become
inhibited, and the most rational treatment is
a progressive strengthening program."
Ideally, says Mooney, such a program is best done
with calibrated equipment that allows the person
with low back pain to gradually increase the amount
of strengthening involved so that performance
and progress can be measured. "With calisthenic-type
exercises, it's very difficult to increase the
amount of exercise that you do, so you do enough
to stimulate repair but not enough to increase
pain," he says.
Florida
chiropractor Thomas Hyde, DC, stresses the importance
of "core stability" in any exercise
program designed to strengthen the back and relieve
chronic pain.
"I like to use the Swiss ball, for example,"
he says. "In the very early stages, the person
may do nothing more than sit on the ball, learning
the basics of what's called 'proprioception,'"
a sense of balance and joint positioning. "Then
they can move on to leg lifts and other various
positions on the ball, to the use of weights or
tubing to do strength training exercises while
on the ball. Over the course of time, the patient
should see an improvement in balance and in their
complaints about back disorders, and it's a relatively
inexpensive approach."
Other types of exercise, such as yoga, Pilates,
and tai chi, are just beginning to be studied
as treatments for back pain, says the GHC's Cherkin.
The preliminary results of a study of yoga for
back pain done at the GHC "looks promising,"
he reports.
Mind and Body
Chronic back pain may not be all in the mind,
but for some people, the answer to conquering
it may lie there. "A number of mind-body
approaches to treating low back pain have demonstrated
success," says Andrew Block, PhD, clinical
assistant professor of psychiatry at the University
of Texas Southwest Medical Center in Dallas and
director of the Well-Being Group, a spine center
in Plano, Texas. "The major approaches are
what we call 'self-regulation strategies': hypnosis,
biofeedback, and relaxation exercises. They're
designed to promote muscle relaxation and pain
control, reducing the amount of energy used for
keeping muscles tight and giving the patient a
sense of control over their situation -- something
you feel like you've lost with chronic pain."
Often, says Block, the image he uses to help a
patient control pain is one of electricity. "I
saw a patient today and we talked about the pain
signals coming up their spine like electrical
wires. When they feel pain, they'll see the wires
glowing," he explains. "As they get
into a relaxed, hypnotic state, they'll see the
glow decrease, visualize it not flowing as intensely
or rapidly, and that enables them to mute the
pain."
Sometimes, it's not about getting rid of the pain
but managing it through other psychological approaches.
"These fall into the category of 'cognitive
behavioral intervention.' You take the thoughts
that go along with back pain and help the patient
change the way they view their situation so that
they can cope with it better," Block says.
"The main thing I advise people to do is
to move from seeing the pain as a condition that
can be cured to a condition of living that requires
them to adapt and function as best they can. It's
important to use your own strength to overcome
what this does to your life."
Ultimately, says the GHC's Cherkin, the choice
of alternative back pain treatment is a very individual
thing. "I don't think any of these approaches
have been shown to be dangerous for low back pain,"
he says. "So it really comes down to what
works for an individual patient and what's worth
trying. It's clear that there's no single treatment
that's effective for everybody."
